(Viaduct demolition photo taken last week by WSDOT)
WSDOT has more information today about the partial Alaskan Way Viaduct closure we reported here last night – including accompanying ramp closures. The main shutdown is 10 pm Monday (December 5) through 5 am Tuesday, but two main access points will close an hour earlier, and there will be some “rolling” northbound effects – read on for details:
Late night and early morning drivers using southbound State Route 99 to get through downtown Seattle will need to temporarily find a new route on Monday night, Dec. 5.
The Washington State Department of Transportation will close southbound SR 99 between the Battery Street Tunnel and the West Seattle Bridge for one night so contractor crews can use the roadway to remove demolition equipment. During this closure, the SR 99 on-ramps at Columbia Street and Elliott Avenue West will also be closed.
Monday’s closure details:
· Southbound SR 99 between the Battery Street Tunnel and the West Seattle Bridge will close from 10 p.m. Monday, Dec. 5 until 5 a.m. Tuesday, Dec. 6.
· The southbound SR 99 on-ramps at Columbia Street and Elliott Avenue West will close from 9 p.m. Monday, Dec. 5 until 5 a.m. Tuesday, Dec. 6.
· Northbound SR 99 between the West Seattle Bridge and the Battery Street Tunnel will have a brief rolling slowdown sometime between 10 p.m. Monday, Dec. 5 and 5 a.m. Tuesday, Dec. 6.
During the last few weeks, crews have been demolishing the remaining 1,100 feet of the viaduct’s south end. Once this section is removed, crews will begin to prepare the work zone for SR 99 tunnel construction. To learn more about this project, go to www.wsdot.wa.gov/projects/sr99/tunnel.
